- Chaos & Complex Systems Seminar
- Clouds and aerosol: their role and impact in the atmospheric and global climate processes
- Time: 12:05 pm
- Place: 4274 Chamberlin (Refreshments will be served)
- Speaker: Pao K. Wang, UW Department of Atmospheric and Oceanic Sciences
- Abstract: Atmospheric clouds have great impact on the global climate process mainly due to their ability to influence the radiative budget of the earth system. But because of their high variability, they also make climate predictions complicated and unreliable so far. In addition, cloud formation is closely related to the aerosol in the atmosphere. This further complicates the climate predictions because we don't yet fully understand how clouds and aerosol interact and meanwhile human activities keep injecting large amount of aerosol into the atmosphere. In this talk I would like to discuss fundamental cloud and aerosol interactions and how they may impact the global climate process.
- Astronomy Colloquium
- Fueling Galaxies at z = 0
- Time: 3:30 pm
- Place: 6515 Sterling Hall
- Speaker: Mary Putnam, Columbia University
- Abstract: Spiral galaxies are thought to have a source of incoming star formation fuel through the majority of their lifetimes. This fuel source includes satellite galaxies captured by the galaxy and possibly clouds condensing within the galaxies extended hot gaseous halo. Some galaxies may also be fueling themselves by transferring gas from the outer regions to the inner star forming disk. The evidence for various fueling mechanisms and the future fueling prospects for the galaxies of the Local Group will be discussed.
- Host: Professor Snezana Stanimirovic
